HANsnN, a residing at Aberdeeinin the county of Brown and State of South Dakota, have invented new and useful Improvements in Automatic Punching Devices, of which. the following a specification.

This inventionrelates to punching devices, particularly toa mechanism of this character designed to be used in an ordinary printing press, and has for its object the provision of a punch which is designated to be disposed upon the front. of a; printing press and which is type high so as to be engaged by the impression plate of the press for effecting the punching operationwithout necessitating any adjustment of the impression controlling screws on the'printing press.

An important object is the provision of a punch of this character which is mounted upon a feed plate secured upon the press platen by means of platen bails such as are used for holding the ordinary tympanupon the platen. j I

Still another object is the provision of a punch of this character which will automatically operate to punch holes through a large number of sheets of paper, the holes being of any desired number and of any preferred shape, the device being furthermore of such formation that the vpaper to be punched is fed thereinto in exactly the same manner as paper is fed into the press during an ordinary printing operation.

A still further object a punch of this character in which the female die member has associated therewith a slidable waste carrier which automatically ejects the pieces of paper out out by the male die Be it known that I, AUsUsr at each stroke or closing of the press, the

engagement of the impression plate with the punch. deviceoperating this waste slide.

Yet another object is punching device in which the parts may be readily disassembled for effecting. interchanging or whereby to permit of making repairs or adjustments which may be 'necessary to keep the device in thorough opera tive condition a novel clamping means being provided for normally ,holding the parts iii certain relative position.

'--A.n additional object isthe provision of a punch of this character. which will be comparatively simple and inexpensive in manuis the provision of designates the the provision of a the press to be punched.

facture, easy to install and use, rapid in v a t action, durable inservice and ageneral impi'ovenien't in the art.

WVith the above and other. objects and advantages in view, the inventionfconsists: in the details of constructionto be hereinafter more fully described and claimed, and illustrated' in the accompanying which, I

Referring more particularly to the drawings the letter A- designates the presser. or stationary plateof printing press and movable platen, In carrying out my invention lf provide an elongated feed plate Hi from he ends of wliich extend 11 upon one "of which. is pivoted, as shown at 12 a lock bar13 whichhas itsother and adapted to be secured to the, other arm 11 by ineaiisof, a screw 14: orthe like; This feed platelO is designed to be secured upon the platen B of the press and tofbe held thereon, by means of theusual platen bails indicated by is a side elevation of myv punch" any the letterrG The feed plate 10 a plurality ,Q holes 16.

bar 13 and held at the desired position thereon by means of suitable set screws 19. In disposing the punch proper upon the feed plate it is of course necessary thatthe screw, 14 be removed and the lock. bar 13 be swung away from the plate '10 so that the' punch proper may be engaged upon the bar whichhas its forward edge extending beyond the-oif-set portion 22 and inclined upward-1y whereby to define a flaring entranc tothe slot 23. The base portion of the punch proper further includes a die plate 25 which is formed with a hole 26 constituting the female die of the device The corners of the upper portion of the offset bracket 22 are provided withrecesses 27 for a purpose to be described. It should also be stated that the top of the oil-set bracket portion 22 is formed with spaced recesses 28 within which are engaged coil springs 29, the

bracket portion being furthermore provided with a hole 30'registering with the hole 26 in the die-plate 25.

Pivoted' between ears 31 formed on the base of the punch device is an inverted U- shaped' frame 32 which has its upper or bight portion engaged by an elongated tongue 33 formed on an impression plate 34.; which carries a male die 35 passing through the hole 30 and adapted to beprojected through the hole 26. Projecting from the underside of the impression plate are dowel pins 36 which engage the coil springs 29 whereby the impression plate will normally be urged into its uppermost position with the male die disposed out of obstruct-v ing relation to the paper receiving slot 23.

In order to limit upward movement of the impression plate with respect to the .base of the punch, such upward movement being urged bythe spring 29,1 provide the-impression plate 34 with depending side portions 37 which are slidably engaged against the 'endsof the offset bracket portion 22 andwhich terminate in laterally directed; flanges 38 engaging against substantially Ll-shapedspring clipsor clamps 39 which are formed" intermediate their ends with loops 4C0 constituting handles and which have the. terminals-of their armsinwardly directed as indicated at 41 and engaged within the. recesses. 27'. at the corners efthe manly. it, will be the hole 26in the die plate 25 for receiving the pieces of paper cut outby'the cooperat-v ing male and female dies 35 and 26 respectively. The plate 42 is formed with an upwardly extending ear 45 whichis dis-posed i I within the frame 32 and which isprovided with a hole 4 6 for the passage of a guide. rod 47 which projects from the backof the offset bracket 22 and'which is SUIIOUHClQClilY a coil springl-S which has one end abutting against the bracket and its other end abutting against the car 45. This spring-48 operates to hold the frame 32 in normal position in engagement with the impression plate 34; aswill'be readily apparent. At its underside the plate 42 is formed with a transverse rib4t9 which is flush with the underside of the base 17. y I

Assuming that the device has been constructed and assembled as above described and illustrated in the drawings, the opmi is as follows:

Thefeed plate 10 is secured uponthe press platen and is held thereon by means of the bails C. The screw-14 is removed to permit swinging of the bar 13 and the punch proper is disposed in association with. this bar. 13 by engaging the bifurcated arms 1.8upon the bar 13 and securing. them in position along the bar at any desired location "by means of the set screws 19. The bar 13 is then swung to normal. or initial position and the. screw 1'4.- is inserted for holding the bar" at the proper place rigidly with respect to the-plate 1:0. The side guides 15 mustof coursebe so disposed within oneof theholes 16in the feed plate as to bring, the paperfed" into the device at the proper point to be punched. As the press is open, paper .is-fedinto the slot 23, being properly guided thereinto by the side guide 15. the platen oft-he press is moved toward the stationary or presser plate thereof,,it will be apparent thatthe eng cement of the impression plate 3 against the plate A will cause the impression plate to be moveddown into engagement with the cit-set bracket owing to the fact that the deviceis type high, and will in urally result in forcing the male die the hole 26 constituting the female die so ti a hole will be punched through all the pieces of paper located within the slot As. the impression plate 34 is forced toward the base, the engagement of the tongue with the 32 will cause the at is new ts'p ite nd as a result in forward movement of the waste plate a2 so as to bring the slot 44 therein into registration with the female die hole 2650 that the pieces of paper out from the sheets being punched will pass into the slot 44;. As the press subsequently opens it is apparent that the springs 29 will operate to return the impression plate to normal position, that is forceit away from the frame and bracket 22, thisoutward movement being limited by the engagement of the flanges 38 with the spring clamps 39. As this movement of the impression plate occurs it is apparent that the frame 3 2 will return to its normal position under the influence of the spring 48and this will resultin rearward movement of the waste plate 4.2 so that-the rib 49 thereon will move rearwardly the little pile of small punch.

pieces of paper punched from the sheets and owing to the fact that the rear end of the slot as is open it will be apparent that the waste pieces of paper will. slip out and fall through the press instead of accumulating and cloggingthe action of the punch. This action is contlnuous as long as thepress is in operat1on, a punching action being offected every time the press is closed, and the in association with a platen printing press.

(ill

lVhile I have shown the die members as being circular it is of course to be understood that they may be of any desired shape and that any number of die members may be used. It is also to be observed. that in case it is. so desired the impression plate 84 may be removed by disengaging the spring clamps 39 from the bracket member 22 by the simple process of disengaging the inwardly directed ends 4.1 of the clamps from the recesses 27 in the bracket "22. It is also to be observed that I may use a plurality of the punching devices associated with the bar 13 and held thereon at the desired points so that a comparatively large number of punches may be made simultaneously when such is desired. It is also to be noted that the positions of the punch members may be varied along the bar 13 and these positions may be maintained set by means of the set screws 19 which operate to lock or secure the punches at any desired point.

While I have shown and described the preferred embodiment of the invention, it is of course to be "understood that I reserve the right to make such changesin the form, construction and arrangement of arts as will notdepart from the spirit of t e invention or the scope of the subj'oined claims.
